CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 427,371, dated May 6, 1890. Application filed March 3, 1890. Serial No. 342,884. (No model.)

To aZZ whom it may concern.-

Be it known that I, EVERETT SCOTT, of Roarin g Creek, in the county of Randolph and State of \Vest Virginia, have invented certain new and useful Improvements in Automatic Car- Couplings; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in automatic car-couplings; and it consists in the combination of the draw-head with a slotted notched frame secured to the under side of the draw-head and a sliding and verticallymoving link-support which is placed therein, and which holds the outer end of the link in a raised position and is forced back out of the way just as the cars couple, as will be more fully described hereinafter.

The object of my invention is to provide an automatic car-coupling with a link-support which holds the outer end of the link in a raised position when a high and a low car are to be coupled, and which support, when not desired, can be pushed back out of the way, so as to let the front end of the link incline downward.

Figure 1 is a side elevation of a car-coupling which embodies my invention complete, a portion of the front end of the draw-head being broken away, so as to allow the linksupport to be shown in one position in solid lines and in another position in dotted lines. Fig. 2 is a plan view of the draw-head,the inner portion of the pin-support being shown in dotted lines.

A represents the draw-head, which is provided with the raised portion B upon its top, and which serves as a support for the pin when -it is in a raised position. Pivoted in one side of this draw-head is the link-support B, which has its inner end to move through a portion of a circle, so as to move back and forth under the pin D, and has its outer end to project beyond the side of the draw-head, where it forms a-handle for the purpose of operating the support so as to set the coupling. WVhen the inner end of this support is moved forward, it passes under the pin-hole,

and the pin then rests upon it until the link enters and pushes back the support and allows the pin to fall.

Secured to the under side of the draw-head or formed as a part thereof is the slotted guiding-frame G, which is provided with a vertical notch or recess II at any desired point. Placed inside of this slotted and notched frame is the link-support I, which is provided with shoulders J near its upper end for the purpose of holding it in a raised position upon the top of the frame G. \Vhen this link-support is raised sothat the shoulders J are above the upper edge of the frame, the link support can be moved forward through the slotted portion of the frame into the front end of the draw-head,where 1t forms a support for the coupling-link for the purpose of holding the outer end of the link in a raised position, so as to adapt a low car to couple with a high one. IVhen this support is not needed, it sinks into the notch H, and then its upper end is below the bottom of the draw-head, where it is entirely out of the S ecured to or formed on the under side of the coupling-link L is a suitable projection O of any suitable description, and ust beyond the projection is a suitable recess P, into which the upper end of the link-support sinks. When the link is forced back into the drawhead, this projection strikes against the upper end of the link-support and forces itbackward over the curved upper surface of the frame G until it sinks back into the recess II.

The recess in the under side of the link causes the link to rest upon the top of the support without any danger of becoming misplaced, and the rounded surface of the frame G upon each side of the slot causes the llllksupport to slide forward to the front end of the frame, where it is not likely to be-misplaced until the projection on the under side of the link forcibly moves it backward into the notch H. In case it desired to couple a high car to a low one this link-support is moved back into the recess H, where it is not brought into play. The lower edge of the frame G is also inclined downward toward the front end, which makes the frame just thick enough at this point to fill the space upon the link-support between the shoulders J and the pin P, which is passed horizon- I tally through its lower end to prevent vertical displacement. If the coupling-pin is once passed through the link and thelink-support is raised into position, the projection 0 will bear against the outer upper edge of this support, and then when the link is forced backward the link-support is forced back into the notch H. From the above it Will be seen that the link-support has a vertical movement, so as to have its upper end raised out of the recess H, and has a horizontal sliding movement, so that it can be moved back and forward in the slot in the front end of the frame G.

The link may be made perfectly straight, or it may be bent at its center, so as to better adapt it for coupling high and low cars. I

Having thus described my invention, I claim- 1. The combination, with an automatic carcoupling, of the slotted notched frame G, the 1iuksupport, and the coupling-link provided with projections on its under side for forcing the pin-support back into position, substantially as shown.

2. The combination of the frame G, provided with a slothaving rounded upper edges, and the recess H with the headed link-support which passes down through the frame G and has both a horizontal sliding and a vertical movement, and the link-support provided With projections on its under side, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EVERETT SCOTT.
